Introduction to Zero Trust
The modern enterprise operates in a dynamic environment where users connect from anywhere, applications run in the cloud, and data moves freely across ecosystems. This has shifted the central question for security leaders from "Who can we trust" to "How do we verify everything, everywhere?" Zero Trust has emerged as the corrective strategy to this reality, replacing static, perimeter-based controls with continuous validation of every user, device, and session. However, despite near-universal acceptance, Zero Trust execution remains uneven, with a widening gap between strategic intent and operational reality.
The Challenge of Zero Trust Execution
The 2025 Zero Trust Report reveals that organizations know what Zero Trust requires but struggle to enforce it consistently across hybrid and multi-cloud environments. The challenge is no longer conviction, but integration: unifying fragmented tools, policies, and signals into one adaptive security fabric that enforces continuous verification from edge to cloud. The report highlights the importance of simplifying through SASE and accelerating with AI to break through the obstacles to Zero Trust progress.
The Exposure Layer: Over-Privileged Access
Even as Zero Trust becomes a strategic priority, most organizations are discovering just how much implicit trust still remains in daily operations. Over-entitled user accounts, inconsistent SaaS permissions, and unmanaged devices continue to create silent pathways for attackers to blend into legitimate traffic. The survey data reveals that 56% of organizations cite employee over-privilege as the leading contributor to unauthorized access, followed by SaaS and cloud applications at 48%. Closing these gaps requires secure connection and continuous verification, automatically adapting or revoking access as risk changes.
From Intention to Impact: How CISOs Are Redefining Zero Trust
Security leaders are reframing Zero Trust as more than a defensive architecture – it’s becoming the foundation for operational agility. The goal is no longer just to stop breaches, but to make security an enabler of speed, scale, and innovation. The data reflects this shift, with 63% of respondents citing reduced security risk and breach impact as the top outcome driving their Zero Trust and SASE strategies. CISOs want architectures that not only harden the enterprise but also remove friction from change, supporting cloud migrations and site rollouts with consistent policy and user experience.
Many Paths, One Destination: The Starting Points of Zero Trust
Zero Trust transformation rarely begins from scratch, with most organizations modernizing along distinct technical paths to relieve the most immediate source of friction on the road toward unified security. The survey data shows that 30% of organizations take an access-first approach, replacing legacy VPNs with Zero Trust Network Access (ZTNA) and introducing per-application connectivity for private apps. Another 26% pursue a platform-first path, consolidating access, inspection, and data protection early through integrated SSE or SASE architectures.
How SASE Operationalizes Zero Trust at Scale
SASE provides a delivery architecture for Zero Trust, converging networking and security into a single, cloud-delivered framework that enforces identity- and context-based policy wherever users and data operate. The survey data confirms that 34% of organizations favor a single vendor SASE platform, while 29% pursue a hybrid approach, showing that nearly two-thirds are consolidating rather than diversifying. By converging SD-WAN and SSE into a unified, cloud-delivered SASE fabric, organizations can simplify operations, reduce tool sprawl, and enforce continuous verification across all access paths without added latency or user friction.
The Integration Wall: Why Zero Trust Progress Stalls
Even with clear strategy and the right architectural model in sight, many organizations remain trapped in operational complexity. The survey data reveals that tool and vendor sprawl ranks as the single largest barrier to advancing Zero Trust and SASE, cited by 26% of organizations, ahead of both budget and legacy technology. SASE directly addresses this integration wall by converging SD-WAN, SSE, and Zero Trust controls into a single policy fabric, replacing tool coordination with automatic policy inheritance.
Simplification as Strategy: The Turn Toward Unified Architectures
The survey clearly shows that the industry is pivoting from diversification to consolidation, with nearly one in three respondents citing unified platform adoption as the key to accelerating their Zero Trust and SASE progress. Unified architectures remove friction between networking and security teams, create a single policy source of truth, and enable faster change across sites, clouds, and remote users. By simplifying first and then scaling safely, organizations can unify identity, device, and network enforcement under a single, cloud-delivered policy plane.
Universal ZTNA: The Execution Engine of Zero Trust
Universal ZTNA becomes the operational core of a modern security fabric, extending the principles of least privilege and continuous verification to every user, device, and application. The survey findings confirm that 82% of organizations view Universal ZTNA as essential to their security strategy, yet execution lags dramatically, with only 17% having fully implemented Universal ZTNA. By converging SSE and NAC under a single, cloud-delivered policy engine, Universal ZTNA simplifies operations and reduces tool sprawl, enforcing per-session verification across all access paths without added latency or user friction.
Beyond Access: Extending Zero Trust Across the Enterprise
The next stage of Zero Trust maturity isn’t about adding new tools, but about applying the same principles across the enterprise. Once identity, access, and policy are unified through architectures such as SASE and enforced by Universal ZTNA, the focus shifts to coverage: extending those controls with equal precision across users, devices, data, and workloads. The survey data shows that identity and access remain the top priority for 71% of respondents, but security leaders are now extending Zero Trust logic deeper into the environment, with device and network enforcement ranking at 64%, cloud and SaaS security at 61%, and data protection at 57%.
AI: The New Force Multiplier
AI is transforming how security operates, analyzing telemetry at scale, detecting anomalies, and dynamically adapting controls based on behavioral context. In mature environments, AI doesn’t replace human judgment but instead augments it through intelligent copilots that assist analysts and administrators, automating routine tasks, surfacing insights, and suggesting actions in real time. The survey results highlight how quickly this shift is accelerating, with 56% of organizations already using AI or machine learning for threat detection and response, and 42% applying it to policy automation.
From Fragmented to Unified: The Zero Trust Execution Matrix
The findings from the survey are clear: Zero Trust works best when it’s unified. Complexity, overlapping tools, and inconsistent enforcement remain the chief obstacles to progress. The first step is always visibility: map who and what connects, then modernize one access path at a time to prove the model and build momentum. Organizations advancing fastest are simplifying architectures, unifying identity and policy under a single control plane, and applying automation to keep protection both continuous and invisible. The path forward is clear: simplify the architecture, unify enforcement, and amplify with intelligence to make protection adaptive.
